HPMC Hydroxypropyl Methylcellulose for dry mortar
HPMC Hydroxypropyl Methyl cellulose for dry mortar
We are the professional manufacture for Hydroxypropyl methyl cellulose in China.
1. Product Introduction
Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose used in building materials, which can be dissolved in hot or cold water to form a transparent solution with a specific viscosity.
Normally HPMC is widely used in dry-mixed mortar industry, ceramic tile binder, external insulation system, self-leveling mortar, plastering, putty, paint and so on, it can improve construction performance, water retention performance, bond strength and sagging resistance.

HPMC advantage
1. Thickening: methyl cellulose ether can thickening has been suspended, and solutions to maintain uniform and consistent action, flow resistance to hang. Methyl cellulose ether of thickening property has also been widely used in drug coating system grain of eye drops, etc.
2. Water retention: in construction industry of putty powder dry slow, auxiliary gray calcium in water under the effect of the reaction. In the external insulation wall jointing agent self-leveling mortar and other areas to be widely use.
3. Construction: methyl cellulose lubrication, can let putty powder has good workability. The greatest degree of saving feeding cost increase of plaster daub area.
